I think this is an issue w/ cups 1.7.* on all platforms; there's a patch that's been merged, and I will bump the gem version today, promise!

[bigtunacan]

I pointed to master and tried a bundle install and I'm still getting the same errors.

[bigtunacan]

Any update on this?

[bigtunacan]

Been about 6 months now; any chance this will get fixed?

[bigtunacan]

I cloned the repo to try and look at this issue and found out it is only happening if you point to the gem on rubygems or git. When referencing a local path it appears to install ok.

[m0wfo]

@bigtunacan glad you found a partial solution; sorry but I'm not using this gem right now and don't have time to do anything other than test PRs.

[bigtunacan]

I'm submitting a pull request that fixes this issue and have tested for backwards compatibility to Ruby 1.8.7 on Mac OSX Lion.

This also fixes issue #12

@m0wfo If you could bump the version and update this on rubygems that would be greatly appreciated.
